Tennis, one of the original launch-era Game Boy titles and one of the purest early demonstrations of Nintendo’s handheld vision. What makes it especially memorable is its place in Game Boy history: it was among the first games to show off the system’s link cable multiplayer and became closely associated with the hardware’s social appeal. It is also widely remembered for Mario appearing as the umpire, giving this otherwise straightforward sports title an unmistakably early-Nintendo charm.
